Head over heels
Deeply romantically attracted to someone, with strong feelings of affection and attachment: She's been in love with him since college.
The phrase implies emotional investment beyond mere attraction—you can be attracted to someone without being in love with them.
Extended to passionate enthusiasm for things: He's in love with the sound of his own voice.
